I want to clean the engine and engine compartment. I have had several c4s and water did horrible things to the sensors and electrical system. Is that the case with a 71? Can I power wash it? What about simple green and hose?
Wrap your distributor and carb well in plastic, spray everything down with degreaser and brake cleaner, and pressure wash what you can. If you have wires or hoses that fail during this process then they needed to be replaced anyway.
ok my 81 has some computer crap in it...so is that safe for me too?
Yes, but disconnect the battery before doing this...which applies to even early carbed cars...and cover as many of your electronic components as possible.
Im from the old school I guess, we always let the motor run and if it started to bog we would quit spraying that spot . These all had very few connectors though. not like the shi":> loads we have now days.
It really very simple. If you want to clean the engine and not do any damage to anything...remove the engine, clean it all up and put it back in. And while you're at it.............
If you feel you must do it, be VERY very careful.
The chemicals used to "degrease" do just that...Very well. Were talking about litterally drying up the innards of your distributor, starter, (distributor) HEI. (I had to buy a new starter, Alternator & new coil)..."Got Cash?"
Believe me, this stuff has grease intentianally put in there...Yes, even your ditributor. The degreaser will kill it. [speaking with personal experience here ]
Not to mention, rubber & plastic is primarily made from...Oil based products. You are litterally drying & prematurely killing all plastic, rubber, hoses & fittings.
-I'm sure some detail guys will agree with me here, as I am almost certain some other detail guys will flame me. I'm just giving you my own personal experience.
I have always been told Simple Green and a hose are adequate for an engine that isn't covered with gunk. The more aggressive de-greasers do run the risk of damaging wires, hoses and engine paint.
Okay, so considering the careful aspect of not using degreaser...how do you suggest someone clean their engine bay?
I have done it several times in multiple vehicles with no adverse reactions.
Well, if it's a dirt ball, then just have the engine bay professionally steam cleaned. That will, however, remove a lot of the paint from the engine. That may not matter since you will probably want to paint the engine after you've removed the crud. When repainting an engine in the car, aluminum foil can be used to mask pieces you don't want to get overspray on. If it is just dirty then less aggressive cleaners will produce good results with either a hose and pressure nozzle or a coin op car wash (my personal preferance). This will generally leave you on non-speaking terms with the guy who owns/manages the coin op. The best approach is to paint the engine out of the car, but I sure wouldn't pull an engine just to paint it unless the car was being prepared for concours competition.

I like simple green
I also use hand cleaner...gojo...or some thing along those lines....works great and only goes where you put it.
I do this on hoses or what ever ....orange makes it smell good too.
